A live dashboard for anything that can send a request.

Build me a live dashboard with InstantGUI (https://instant-gui.com): a free web board that scripts, devices and AI agents create and update over plain HTTP. No signup, no API key.

First, ask me what I want to see: what it should track, where the data comes from, and which buttons I'd want (pause, restart, run now). Then:

1. Create the board (once):
curl -s -X POST https://instant-gui.com/api/v1/boards -H 'Content-Type: application/json' -d '{"title":"My dashboard"}'
→ {"board":{"id":"<board>",…},"editLink":"…","writeToken":"<token>"}
Keep board.id and writeToken; send "Authorization: Bearer <token>" on every call. Give me the editLink: it opens the board for me (anyone with it can edit, so don't post it publicly).
If I already gave you an edit link (…/b/<board>/join?key=<edit key>), skip this step and use the edit key as <token>.

2. Declare every widget in ONE call (this example is a shop; replace it with what I asked for). It is idempotent: send it again whenever the layout changes. Grid is 12 columns, rows ≈ 52px.
curl -s -X PUT https://instant-gui.com/api/v1/boards/<board>/spec -H 'Authorization: Bearer <token>' -H 'Content-Type: application/json' -d '{"title":"Shop live","widgets":[{"key":"revenue","type":"kpi","title":"Revenue today","layout":{"x":0,"y":0,"w":4,"h":3},"config":{"prefix":"$","icon":"wallet"},"data":{"value":4820}},{"key":"ads","type":"actions","title":"Ad campaign","layout":{"x":0,"y":3,"w":4,"h":2},"config":{"buttons":[{"id":"pause","label":"Pause ads","tone":"danger"},{"id":"resume","label":"Resume ads","tone":"success"}]}},{"key":"revenue-trend","type":"line","title":"Revenue per day ($)","layout":{"x":4,"y":0,"w":8,"h":5},"data":{"series":[{"name":"revenue","points":[["2026-10-08",4100],["2026-10-09",4390],["2026-10-10",4820]]}]}},{"key":"orders-log","type":"log","title":"Recent orders","layout":{"x":0,"y":5,"w":12,"h":4},"data":{"entries":[{"t":1760000000000,"text":"#1045 · $129.00 · Organic","level":"success"}]}}]}'
Widget types: kpi / stats (numbers), gauge / progress, line (trends), bar, pie, table, status (health), log, actions / button / toggle / slider (controls), markdown (one short headline at most). Use real data, not samples.

3. Keep it live: push by widget key whenever a value changes.
curl -s -X POST https://instant-gui.com/api/v1/boards/<board>/widgets/revenue -H 'Authorization: Bearer <token>' -d '{"value": 5010}'
curl -s -X POST https://instant-gui.com/api/v1/boards/<board>/widgets/revenue-trend -H 'Authorization: Bearer <token>' -d '{"append": {"revenue": 5010}}'
curl -s -X POST https://instant-gui.com/api/v1/boards/<board>/widgets/orders-log -H 'Authorization: Bearer <token>' -d '{"append": "#1046 · $54.50 · Email"}'
Then write me the script or cron job that keeps pushing real values.

4. Check the design: curl -s https://instant-gui.com/api/v1/boards/<board>/lint -H 'Authorization: Bearer <token>'  and fix every warning.

5. Buttons: read what I clicked with curl -s https://instant-gui.com/api/v1/boards/<board>/widgets/ads -H 'Authorization: Bearer <token>' (data.lastAction), or set config.webhookUrl to get a POST on every click.

Rules: numbers and charts over text; most important widget top-left; title every widget with its unit ("Revenue today ($)"); always include the actions I'd want next.

Prefer tools over curl? Add the MCP server: https://instant-gui.com/api/mcp (Claude Code: claude mcp add --transport http instantgui https://instant-gui.com/api/mcp). Tools: apply_board_spec, push_data, lint_board.

When it's live, send me the editLink.
